CAR-WHEEL-FLANGE LU BRICATOR.

Specification of Letters Patent.

Patented April 17,1906.

Application filed August 23, 1905. Serial No. 275,447.

To all whom, it may con/cern:

Be it known that I, ANDREW C. LOvE, a citizen of the United States, residing at Sacn ramento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Car-Wheel- Flange Lubricators, of which the following is a speciiication.

My invention relates to devices for lubricatio ing the anges of car-Wheels in rounding curves.

At the present time the practice is to apply grease to the bearing-surface of railsin curves. This practice is objectionable, because the i 5 grease rubs off onto ladies apparel and in hot weather melts and runs down into the groove of the rail as used on urban surface trolleyroads or off of the flange altogether of suburban trolley and steam railroads, thus neceszo sitating regreasing the rails.

In my invention the lubricant in the shape of a liquid is carried on the car and is conveyed to the flanges of the Wheels by means of pipes ending in nozzles situated to distrib-l ute the oil to the wheel-anges. The flow of oil is controlled by means of a valve so placed and constructed that it is opened by the action of the car in rounding the curve and closed by a spring as soon as the car leaves 3o the curve.

The construction of my invention will `be specifically described hereinafter and illus# trated in the accompanying drawings, in which- Figure 1 is a view showing the end of a car and a truck showing my improvements'in position and the parts in position when running on a straight track; Fig. 2, a similar view showing the positions assumed in round- 40 ing a curve; Fig. 3, a side view; Fig. 4, an enlarged view, partly in section, ofthe valve,

showing it closed and Fig. 5 a similar view showing it open;

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A represents a beam across the front end of na car-body B, the truck, which is swivelly mounted relative to the car-body.

C represents a pipe connected with a tank (not shown) to convey oil from said tank to cross-pipes D, having at their ends nozzles E, directed at the flanges of car wheels B', mounted on truck B. y

F represents a valve situated in the joint of pipes C and D to control the flow of the oil to the nozzles E.

G represents the valve plunger, I-I the stem, and I the coil-spring to keep the plunger normally seated in the valve.

J represents a block pivotally secured to the stern and so formed that when rocked, as

shown in Figs. 2 and 5, the plunger is raised from the valve-seat.

K represents L-shaped arms having slots lc therein, and L a bolt for securing the arms to block J.

M represents a rod secured to beam A and extending downward between arms K.

In operation the parts being in the position shown in Fig. l, the valve F is closed, but when the car runs onto a curve the truck swings on the car-body, and the rod M, contacting with one of the arms K, the valve is opened and oil passes through pipes C and D to nozzles E, and the flanges of wheels B are lubricated. As soon as the car runs into a straight track again the pressure of the rod M on arm K is relieved and the spring I reseats the plunger, closing the valve.

Having thus described my invention, what I claim is- 1. In combination with a car-body and a swiveled wheeled truck thereon, pipes for `conveying a lubricant to the wheel-flanges, a

valve for controlling the How of the lubricant through said pipes, and operative connections between said valve and the car-body, substantially as shown and described.

2. In combination with a car-body and a swiveled wheeled truck thereon, pipes for conveying a lubricant to the wheel-flanges, a valve for controlling the How of the lubricant through said pipes, a rocking member for opening said valve attached to the stem thereof, and operative connections between said rocking member and the car-body, substantially as shown and described.

3. In combination with a car-body and a swiveled, wheeled truck, pipes for conveying a lubricant to the Wheel-flanges, a valve for controlling the flow of the lubricant through said pipes having a spring-actuated plunger, a rocking member secured to the valve-stem, arms secured to the rocking member, and a rod secured to the car-body and adapted to engage said arms and open the valve, substantially as shown and described.

4. In combination with a car-body and a the arms and open the Valve, lsubstantially as 1o swiveled, Wheeled truck, pipes for conveyshown and described.

ing a lubricant to the Wheel-flanges, a valve for controlling the flow of the lubricant through said pipes having a spring-actuated plunger, a block pivotally secured to the valve-stern, L-shaped arms having a slot therein secured to said stern, and a rod secured tothe car-body and adapted to engage In testimony whereof I hereto aiiiX my signature in the presence of two witnesses.
